UCM1E272MNS1MS

The UCM1E272MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount radial can package. With 2700 µF capacitance at 25 V and design features for automated assembly, it addresses demanding power filtering and energy-storage needs in electronics systems.

Engineered for robust operation across −55 °C to +105 °C and AEC-Q200 qualification, this part is targeted at automotive and other high-reliability power applications that require high capacitance, elevated ripple handling, and long-term endurance.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 25 V with ±20% tolerance for reliable bulk energy storage and smoothing.
• Low Impedance Performance — Specified loss tangent (tan δ) of 0.16 measured at 20 °C, 120 Hz for the 25 V rating, supporting stable AC performance.
• High Ripple Current Capability — Low-frequency ripple current 955 mA at 120 Hz and high-frequency ripple current 1.91 A at 10 kHz to handle switching and transient loads.
• Leakage Current — Specified leakage current of 675 µA, enabling predictable static current behavior after voltage application.
• Wide Temperature & Long Life — Operating range −55 °C to +105 °C with a rated lifetime of 5000 hours at 105 °C, suitable for extended duty at elevated temperatures.
• Automotive-Grade Qualification — AEC-Q200 qualified for designs requiring automotive-level component qualification.
• Surface-Mount, Assembly-Ready Package — Chip-type radial can (φ16 × 16.5 mm length) designed for surface-mount placement and supplied in embossed carrier taping for automatic mounting.
• Vibration Resistant — Vibration-resistant construction to support mechanically demanding environments.
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing in vehicle power modules where AEC-Q200 qualification and extended temperature range are required.
• DC–DC converter output filtering — High capacitance and 1.91 A high-frequency ripple capability help stabilize converter outputs under switching loads.
• Power supply hold-up and transient buffering — Large capacitance and rated ripple currents provide short-term energy support and suppression of supply transients.

Unique Advantages

• High capacitance in an SMD-ready package: 2700 µF in a φ16 × 16.5 mm chip-type can reduces board-level space compared with multiple discrete parts.
• Designed for automated assembly: Embossed carrier taping and chip-type form factor simplify pick-and-place and reflow-compatible handling for volume production.
• Engineered for elevated temperature endurance: 5000 hours at 105 °C supports long-term reliability in hot operating environments.
• Measurable ripple handling: Published ripple current ratings at both 120 Hz and 10 kHz provide clear design parameters for low- and high-frequency power stages.
• Automotive-grade confidence: AEC-Q200 qualification aligns the component to automotive development and validation processes.
• Predictable electrical behavior: Specified tan δ, leakage current, and tolerance enable precise selection and margining in power designs.
